Though the strange salmon cannon has suddenly caught fire, it turns out the quick process of spitting fish through tubes to hurdle over obstacles in water has been a focus of wildlife experts for years.
While human-created dams generate useful, green energy, they disrupt a river’s natural flow, also disrupting the natural spawning runs of the indigenous salmon. Written reports of rough fishways date to 17th-century France, where bundles of branches were used to make steps in steep channels to bypass obstructions.
Vampire bats hunt only when it is fully dark.
Vampire bats, species of the subfamily Desmodontinae, are leaf-nosed bats found in Central and South America. Bats are the only mammals that can fly, but vampire bats have an even more interesting distinction—they are the only mammals that feed entirely on blood. These notorious bats sleep during the day in total darkness, suspended upside down from the roofs of caves, old wells, hollow trees, or buildings.
The average owl flies at a speed of about 10 mph. However, some owls, such as the great horned owl, can reach speeds of up to 60 mph when they are diving for prey.
Owls are birds from the order Strigiformes, which includes over 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight.
At about 6 inches long, it’s the world’s smallest armadillo.
The pink fairy armadillo (Chlamyphorus truncatus) or pichiciego is the smallest species of armadillo. This desert-adapted animal is exclusive to central Argentina and can be found inhabiting sandy plains, dunes, and scrubby grasslands.
The total live biomass on Earth is about 550–560 billion tonnes.
Biomass in ecology is the mass of living biological organisms in a given area, or ecosystem, at a given time. Biomass can refer to species biomass, the mass of one or more species, or to community biomass, the mass of all species in the community. It can include microorganisms, plants, or animals. The mass can be expressed as the average mass per unit area, or as the total mass in the community.
One study found that Douglas firs have the highest theoretical height, but most of the world’s tallest trees are redwoods.
The tallest tree in the world, a California redwood, stands 379 feet tall, or slightly taller than a football field is long. Redwoods of the past that have since been cut down probably stood even taller, and may even have reached the theoretical maximum height for trees.
The Fancy Scientist
Dr. Stephanie Schuttler is a wildlife biologist with 17 years in the field. She started the “Fancy Scientist” blog to share her love of animals, conservation, and science to inspire and connect people to nature. Stephanie grew up in Buffalo, NY. taught by her parents to love animals.
Underwater ecosystems
Back in 1830, the word “Aquarium” (Latin) referred to a drinking place for cattle, like a watering trough. The Victorian mania for the use of indoor aquariums began with the book “The Aquarium,” published in 1854 by English naturalist Philip Henry Gosse[1].
Is there any science behind it?
I expected there to be a straightforward, single answer to this inquiry. But no, this seems to be a mystery. Nocturnally active moths are usually attracted to light sources as you have noticed. This event is known as positive phototaxis.
Some cases contained anomalies that could not be accounted for by conventional wisdom.
Cattle mutilations hit their peak in the 70s when hundreds of cases were reported in Colorado and New Mexico. Because of newspapers, radio, and television, reports were getting to millions of people within a day of the deaths.
